Terrier Max (Patton Oswalt) is coping with some major life changes. His owner (Ellie Kemper) is now married and has a toddler, Liam. Max is so worried about protecting the boy that he develops a nervous tic. On a family trip to a farm, Max and mutt Duke (Eric Stonestreet) encounter canine-intolerant cows, hostile foxes and a terrifying turkey, all of which only elevates Max’s anxiety. Luckily, Max gets some guidance from veteran farm dog Rooster (Harrison Ford, making his animated-film debut),...MORE who pushes Max to ditch his neuroses, find his inner alpha, and give Liam a little more freedom.
